Removal of Escherichia coli from water by systems based on quaternary ammonium salts grafted on 'gel-type' styrene-divinylbenzene copolymers

摘要

Ammonium salts grafted on styrene-divinylbenzene copolymers were obtained by quaternization polymer-analogous reactions. The proposed procedure for preparation are simple and efficient. The functionalization degrees with quaternary ammonium salts are well suited for subsequent use of products as antibacterial agents. This study is concerned with the removal of E. coli cells from water by quaternary ammonium salts grafted on "gel-type" styrene-divinylbenzene copolymers derived from the quaternization polymer-analogous.
